HYDAC泄压阀DB12120A系列功能介绍
The pressure relief valve DB12120A is a direct-acting, spring-loaded poppet valve. Its function is to relieve pressure in the system. It is normally closed. If the pressure at port 1 exceeds the pre-set spring tension, the poppet is lifted off the seat and oil flows from port 1 to port 2.
This continues until the system pressure is equal to the spring tension and the valve closes again.
Important: Pressures at port 2 are additive to the opening pressure! If the connections are incorrect or if the pressure has been set above the operating pressure, the safety function of the valve is disabled.
泄压阀DB12120A是一个直动式弹簧加载提升阀。它的功能是减轻系统压力。它通常是关闭的。如果端口1的压力超过预设的弹簧张力，则提动提升阀芯离开阀座，机油从端口1流向端口2。
这一直持续到系统压力等于弹簧张力并且阀门再次关闭为止。
重要提示：端口2上的压力会增加打开压力！如果连接不正确或压力设置为高于工作压力，则阀门的安全功能将被禁用。
